Okay, I've done some more research... more knowledge leads to new questions I've got the Duncan Designed JB/Jazz... which makes more sense: - replacing the existing 3-way blade switch with a 5-way/4-pole and coil-splitting each pickup; - replacing the existing 3-way blade switch with a 5-way/4-pole and combining outer and inner in parallel; - keeping the existing 3-way blade switch and replacing the tone pot with a push-pull coil-split? Also, what difference in sound will the first two options achieve? I'm a little confused about that. Finally, has anyone ordered from guitarelectronics.com, and if so, what's been your experience? When I order (from wherever), I'll probably replace the cheap pots I have with better ones, and a couple other accessories as well, so I'm open to suggestions about the best way to mod these pickups!
